IMPROVEMENT IN LAMPS.

The Schedule referred to in these Letters Patent and niaking part Of the same.

To all whom it may concern:

Be it known that I, JOHN DUNN, of the city and State of New York, have invented a new and useful Improvement in Lamps and the fiullowing is declared to be a full, clear, and exact description thereof.

In the ordinary method of applying wicks to lampburners, with their lower ends dipping in the oil, a portion of every wick, equal in length to the distance between the oil and bottom of the burner, is wasted.

The object of this invention is to prevent this waste, and for this purpose a secondary wick is connected to the lower part of an ordinary lamp-burner, by a clasp that holds said secondary wick contiguous to the side of the usual lamp-wick, so that the main wick of the lamp can be burned after the liquid hydrocarbon ceases to be in direct contact with the wick.

1n the accompanying drawing, which illustrates my invention- Figure 1 is a central vertical section of a lampburner, and I Figure 2 is a face View of the clasp, by means of which the secondary wick is secured to the burner.

A is the-wick-tube of the burner;

B, the wick to be burnt; and

C, the wick-raiser, of any desired construction.

1) is a clasp, which is soldered or otherwise securedto the lower part of the burner or wick-tube, and made with the slots a and c, transversely of said clasp. The lower edge of the slot 0 is jagged or Formed with teeth.

These two slots form a buckle or clasp for receiving the end of the secondary wick E, so that it is firmly held contiguous to the wick B, and this ivick'E should be long enough to reach the bottom of the reservoir.

The oil passes to the flame by capillary attraction, as usual, and when the wick 13 becomes too short to reach the oil. the oil is transmitted to it by the secondary wick E, which is not consumed, and hence the wick B can be burned till its lower end reaches the bottom of the burner or tube, thus cflecting a saving in the wick and a couveniencein use.

I am aware that a stationary or capillary wick has been employed both in Argand burners and in flatwick burners; therefore I do not claim the same.

The devices heretofore employed have been costly, liable to become detached, or to interfere with the lllOVClDOlltOf the, wickitself. My device is simple, easily applied, holds the capillary wick very firmly, and can be bent, if necessary, so as only to 'bear against the ordinary wick sufiiciently for the transfer of the liquid hydrocarbon.

1 claim as my invention- The clasp 1), made with the slots to and e, and teeth, and attached to the lower part of the burner contiguous to the wick-tube, as and for the purposes spccitied.

Dated this 19th day of August, A. 1). 1870.
